2× Tempest™ 200
Temperature + humidity
Records temperature, relative humidity, dew point, and heat index. Tap each sensor with your phone — no app account, no pairing.
$125.00 $130.00
An essential atmospheric pairing for comparative temperature and humidity auditing between two zones — fridge vs. freezer, supply vs. return, indoor vs. outdoor, or upstairs vs. downstairs.
Two sensors. Identical hardware, identical export schema.
Two Tempest 200 sensors so you can compare the full atmospheric profile of two locations against each other.
The simplest A/B you can run on environmental data — same hardware, same interval, two locations.
One sensor tells you what happened. Two tell you whether it was localized or system-wide.
$5 off the list price. Cheaper than two individual Tempest 200s, identical sensors.
Pharmacies validating two storage cabinets. Restaurants splitting walk-in cooler vs. freezer monitoring. HVAC techs running before/after on a balance change. Homeowners comparing a finished basement to upstairs living space. Anyone whose audit story needs two data points instead of one.
